As a kind of long-range winding system, positioning accuracy of airplane trailing cone automatic releasing system for airspeed calibration relies on linear displacement measurement accuracy of trailing cone automatic releasing process. Comparing several direct and indirect measuring methods, a dynamic long-range linear displacement precision measuring method for winding system based on magnetic rotary encoder is presented. Conceptual design of longrange linear displacement precision measuring mechanism according to proposed method is carried out. After error pre-analysis of several conceptual design schemes, a long-range linear displacement precision measuring mechanism based upon error avoidance theory is designed. The proposed measuring mechanism has been applied to conclude that its high accuracy, reliability and adaptability.
